to all intents and purposes of use,'an ordinary crossing.

, ,The intersection mechanism which forms a continuation of the rails ofeither one track or the other across the inter-section, may be ,briefly described as follows; The rails A andB are securely and permanently attached to-the box structure 10, so as to be stationary; and at the individual rail intersections, where these stationary rails A and B meet each other, they are provided with diagonal end. planes 20, which planes form the surfaces at which the rails A and B meet each other, .and also form the surfaces at which the movable rail; portionsiA and B7 meet the stationary rails- These movable rail portionsvA and B also have similar diagonal surfaces 20 at their ends which bear againsteach other and bear against the surfaces 20,0f thefixed rails A andB.

At each; intersection the diagonal surfaces 20 do not proceed to the center of the; rail intersection; but at the center of each rail intersection thereis a. square block 21 which may be formed integrally with one of the stationary rails. The. movable rail portions A. and B abut this square block 21 as illustrated. Beneath one pair of the movable rail portions, in-this case the rail portions A, I locate horizontal cam shafts 22. These shafts are mounted in terminal bearings 23 and carry the cams 24 which support the movable rails 13. Each movable rail B has supporting beams 25 which rest upon the two opposite cams 24 so that these rail portionsB are supported by the cams, and raisedand lowered by their action.

The cams 30 are also'mounted upon. the shaft the shaft in such a manner as to be relatively movable thereon to change'the-relation of cams 30 to cams 24, for the purpose hereinafter-described.- These cams 30'are accordingly mounted upon sleeves 31 which surround the shafts 22 and may be normally fastened'to the shafts by such means as a screw or plug as shown at 32. These adj ustable sleeves 31 are mounted in the bearings 33, as illustrated. To all. usual intents. and purposes sleeve 31' and its shaft 22 form one solid shaft upon which the cams 24 and 30 are mounted; the adjustability of position f-lof the sleeve 31 on shaft 22 being called vinto play. only is set. to provide an ordinary crossing. Upon each ofthe sleeves 31 mount drum :set and lowerthe second with ,cains 24 foot.

rail portions A .35 and rotatively connect these two'drums by a pair of crossed'chains 36. The vertiregard to theegractstructure of the intersectlOII IDGChEIDlSIIQ. Sufficient has been GX- plained to show the primary features of sucha mechanism, and to show how, byrotation of shafts 22, the action of the cams 24 and 30 is to lower one set of'rails and raise the other setof railsupon rotationin' one direction, andtoraise the first mentioned i mentioned set upon rotation in the otheifldirection, For instance, .in the, drawings the rail portions B" rails B while the rail portionsA. are shown depressed. Uponrotation of theshafts 22,

and 30', the directions indiare shown intheir elevated' positions, in posi-. tions to form continuations of the stationary cated in Fig. 2, and through an angle equal Y to approximately three quarters of a revolution, the rails B will be lowered and railsA. will be raised; 'In oth'er'words the cams 24 and 30, which are essentially duplicates of approximately three-quarters ofa revolution is required; to carry the shaft from a position wherethe highest part ofone cam is beneath a rail foot to; a position where the highest each other, are so placed on the sh aft 'th'atv part of another cam is beneath itsrail,

done, then both and B naay be support-ed simultaneously in theiriippermost position.

Provision for simultaneously supporting the movable ,rail' portions may be made: in 7 other manners For instance, when the lntersectlon mechanism .the pair ofrails A, andrplaee supporting pairs of vertically: movable removable block is i more easily removed, they are also very solidly, supported n wardly inclined. bottom face 51 these side portions straddle but this screw does not carry suchf shape that all intense The rails now all being in their uppermost positions, stationary rails A and B,'it is provide open spaces for the passage ofwheel flanges This is done by providing removable blocks '50, one at each'end ofeach movable rail portion.

A preferred form of conremova'ble block is shown The block 50 has a backstruction' for this a correspondingly inclined surface at upon The block also the end of the rail port1on.i has two downwardly tions 52', as isbest shown in Fig'. 5; and I 'the' web 53 of the 'ra l'an'd' rest attheir lower ends'upon horizontal shoulders 54 of the rail. Ascrew or bolt 55 'serves to hold the block in place any of the It will befnoted that the firmly bedded upon the surfaces 51 and 5 1; and the surface 51 is of weight upon the block tends to'move the blockback against the back operating str ain;

surface 56 rather than to move'the block out" away from the rail portion upon which it is mounted. hus, although the blocksinay be their normal operating position. The outer ends of these blook'sare provided with the bearing hereinbefore described as at t lie ends of the movable rail portions; 1 I 1 I show the rails A: andB each as being made up of beams 7 O in and on which a rail head 71 and web 53 are set and carried ;.being held to the beam by screws 7 2 or the like. In Fig. 5 the block 50is" shown surface 51 which is an uppersurface on web 53,- and resting on shouldersbt which are on the beam 70. Now, the rails A and B may be in ordinary rail form, as shown in Fig. 6; in which case the block 50 rests on the surface 51 as before, but rests, at the lower ends of the side extensions 52, on the upper surfaces of rail flange 7 5 on opposite sides of the rail web 76. Such variations may be made without materially altering the nature of the mechanism.

In Figs. 79 I show another form of block 50 set in the end of the movable rail portion (A) and secured by a screw 60 having a conical head 61 entering a correspondingly shaped opening in the block 50 A suitable lock washer, as at 62, may be used to prevent the screws and block loosening from position. 7

It will now be seen how an intersection mechanism of the character described may normally operate to provide a continuation of either the rails of one or the other track; and how, in an emergency, all the rails may be raised and the blocks 50 removed to form an ordinary crossing.
